Pawn I got from randomizing as a starter colonist is great at constructing, but basically nothing else. I looked at his backstory after a bit to find out why, and it turned out he had the blacksmith backstory as an adult...but a backstory making him incapable of smithing (or crafting of any kind) for his childhood.
I expect pawns to have adulthood backstories that are possible for their childhood backstory-caused incapabilities.

You're right it's weird.
We have allowed this to happen just because
1. Solving it would take a LOT of work
2. Sometimes the combos are amusing.
I'll have to consider what to do here.
Thanks.
